Genomic Data Disclose Potential Information on Evolutionary Interactions among Different Human Populations and Novel Education Technology Development

Abstract

Study on language gene polymorphism patterns (LGPP) across different population genomes could provide incentives to develop novel education technology and important information on human evolution. In this study, as a preliminary observation, we adopted 148 single nucleotide polymorphism (SNP) sites from 13 language genes, each with 4-13 SNPs. These SNPs were screened across 112 whole genome sequences (including 59 ancient genomes ranging from 2000 BP to 120000 BP) from five continents (Africa, Asia, Europe, North America, and South America). We found that five distinct LGPPs featured across human evolution history, in which LGPP-1 may be the oldest version shared by animals and primitive hominins, though data also showed that LGPP-1 is still existing in some modern human populations. Asian and African possessed all LGPP types while European seemed lacking in the LGPP-2. Surprisingly, African samples had a relatively larger evolutionary distance from animals than other populations in LGPP1-4, while in LGPP-5 (the modern human type), some African samples had a relatively small evolutionary distance from animals than other human populations. Except for LGPP-2, all other LGPPs contained Asian, African and European, suggesting that there were vigorous interactions among these three continents all the time during human evolution. In this study, ancient American samples were only found in LGPP1-3, suggesting that either mutual migration among different continents happened much earlier than expected, or ancient Americans had little interactions with other populations after migrating into the America land.
